The last 2 times I filled up the kitty it had about a 1/4 tank of gas but while filling the handle kept shutting off like it was full. I knew it wasn't but even pulling the handle out a little, using the slowest setting it again would shut off. I figured it MUST be full...... but no, upon starting I only had 3/4 tank. Then yesterday, same thing again.... no matter what I did it kept shutting off at the handle and even spit a little out..... and again 3/4's of a tank.


Bad float/sensor/gauge ??


Anyone else have this happen and if so what is it.


TIA,

Same fuel station ??, maybe their pump itself has the problem ?

 

What roviw said. Are you using the same pump and/or station? More likely than not it's the pump itself. Have you tried easing off and not filling it so quickly at the pump? Sometimes filling it too quickly will result in the sensor shutting the pump off prematurely.

 

I've had this happen, but only at Shell gas stations on my previous car, an Infiniti G. So i switched to Chevron and never experienced it again.

 

I think there was a Technical Service Bulletin about this c.2006

Edit: oh, sorry it was diesels only ...

Thinking about it, could it be a problem with the fuel gauge, or the floats sticking (there are two) in the fuel tank ?

 

I turn the fuel pumps handle upside down then trickle it in weird I know but works

My car also has a reducer in the inlet because of unleaded fuel so you cant use the wrong fuel bowser I have tried to remove it then thought if I sell the car It might not pass inspection

 

Thanks for all the input........ yes it was the same gas station. Wasn't the same pump but still it is probably associated to this. I will have to try someplace else next time.

 

The pump nozzles have a hole on the bottom that sense the splash-back to trip the shut-off. I have noticed that the Jag does "splash back" more than other cars, so I often have to turn the nozzle a bit to prevent early shut-off. Of course, some nozzles are also much more sensitive than others.

 

Let us know your findings. Because that was exactly my case!

 

I will second what cjd said, my wifes Mustang does it more then my Jag. Turning the handle upside down most often does the trick.

 

Friends Volvo did this and it was because of some fuel item and vacuum (I know, could I be more vague??).

 

My 98 Land Rover Discovery will hardly take gas, but it is a US big brother required "advanced evaporative system" designed to not let you fill it all the way that is the problem; they only had AV for two years and I have one of the "lucky" years. I have to go to stations with new pumps that can pump very slowly in order to get any gas in it at all. Sometimes disconnecting the vent line to the charcoal canister helps a little. I'll try the upside down nozzle trick next time to see if it makes any difference.

Fortunately the SV8 does not have a problem filling except that it requires it a little too often for my pocketbook; even though it gets way better gas mileage than the Rover I drive it a lot more too.

 

Quick update, it was the gas station. Filled her up today at Costco and took it all, LOL. So apparently the consensus opinion about the pump being the issue was correct. Thanks guys !! Case closed !
